STEERING-WHEEL LOCK.

Application filed J'anuary'29, 1923. Seriai-No. 615,655.

To all whom it may concern:

' Be it known that I, Louis J. Hueuns,

a citizen of the United States, residing at Topeka, in ,the ,county of Shawnee and State of Kansas, f have invented new and useful Improvements in Steering-Wheel Locks, of which the following is a specification. y r

This invention relates to a steering Wheel lock for motor vehicles,.the general object of the invention being to. provide combination means for retaining the locking bolt in locking posit-ion with means for changing the combinations whenever desired.

Another object of the invention is to so arrange the parts that all the screws which fasten the difierent parts in position will be covered by locked parts when the device is in; looking position.

'This invention also consists in certain other features of construction-and invthe combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims. I i

In describing my invention in detaihreference will be had tothe accompanying drawingswherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is an elevation of a steering column of an automobile showing the invention in use.

Figure 2 is a plan view with the steering wheel removed.

*igure 3 is a longitudinal sectional view. Figure 4: is a section on line 1-4 of Figure 3.

Figure 5 is a section on line 5-5 of Figure 3. v

'Figure .6 is a section on line 66 of Figure 3. I -Figure 7 'is a detail view.

In these views 1 indicates the steering shaft, 2 the wheel carried thereby, 3 the column and 3 the gear housing at the upperend of the column. s

In carrying out my invention I place a casing .4: on the housing 3, said casing being secured to a bushing 5 by a screw 6,

the said bushing 5 taking theplace of the cover of the gear housing and being secured in position by the screws 6. This screw :6 is covered by the housing so that it is impossible to remove the screw with the lionsing in place. A locking bushing 7 is keyed to the shaft 1 by the key 8, and this bushing --carries a keeper recess t). This bushing isenclosed by the casing 4 The casing is provided with a tubular extension 10 which forms a bearing for a barrel, 11. The

end of the barrel covers the screw 6 so as to prevent removal of thescrew as long as thebarrel is in. place and saidbarrel is rotatably held on the extension by the screw 12 engaging an annular groove 13 in the extension. 'Both the barrel and'extension are provided with window openings 14. A

.locking bolt 15 passes through the extene sion and through a bore 16 inthe casing and said bolt is held against rotary'movement by means of a screw l-7 carried by the casingand which engages slot 18in the bolt. The inner end of thebolt is adapted to engage the keeperrecess 9 whenforced inwardly by a cam part 19 in the' barrel engaging the head 2Q of the bol t.- The head is provided with arecess 21v for receiving the cam part when the" baIlBl is in a certain position and. the boltis retractedby the spring 22 which is placed upon the head of the bolt and airing 23 which placed in the tubular extension' The combination rings21 engage the bolt and each ring has a key-way 25 therein and an annular groove 26 at one end" which communicates with the key-way and the bolt is provided with a plurality of keys 27 which cooperate with the key-ways and grooves, it being understood that when the keys are inengage- In ent withthe grooves the. rings can be rotated on the bolt and that unless the keyways are in'alignment with each other the bolt cannot be moved. Each combination ring carries an engraved collar 27 which is adjustable to the ring by means of the screw 28 whichengagesa threaded .hole 29 in the ring and a half bushing 30 which frictionally engages the collar when the, screw is tightened and thusv firmly'holds'. the collar t e r s The w m min r a hed by nular recess in the barrel. Thelocking bolt is provided with a recess 36 for receiving the inner end of the pin when the.

bolt is in retracted position which will permit the pin to come into register with a groove 37 in the end of the barrel so that the barrel can be withdrawn, when the bolt is in retracted position, by removing the pin 12. When the bolt is in projected position the pin 33 will prevent removal of the barrel even though the pin 12 has been removed. 1 7

From the above it will be seen that the bolt can be projected by rotating the barrel so as to cause its cam to leave the recess 21 annular grooves 26 in the rings.

in the head of the bolt and'thus force the bolt inwardly against the action of its spring 22. This will cause the inner end of the bolt to engage the recess 9 and thus lock the steering Wheel against movement. Then by turning the combination rings the retraction of the bolt will be prevented. These rings can be rotated when the bolt is in projected position as the keys of the bolts engage the When it is desired to unlock the wheel the combination rings are turned until the proper combinationcharacters are in line with the mark 32 which will place the key-ways in alignment with each other and with the keys on the locking bolt. Then the barrel is turned until the cam comes opposite the recess 21 in the head ,ofthebolt and then the spring 22 will retract the bolt. 'To-lock the wheel again it is simply necessary to turn the bar- 7 reel to project the bolt and then return the combination rings ;to lock the bolt in projected position. The barrel is provided with knurled rings 11 for facilitating its rotation. As before stated the fastening screws are all covered so that it is impossible to unlock the steering wheel by disassembling the parts though the parts may be disassembled when'the locking bolt is in retracted position.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall with in the scope of the appended claims.
